The winter grain mite Penthaleus major (Dugés) is now occasionally observed as a summer pest in the cold temperate zone, especially in subarctic hayfields. The life cycle of the mite was studied from pitfall trappings in 19 hayfields at 10 farms in Eyjafjordur in northern Iceland throughout the summ...
